<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Maybe this should be a functionality available for all layers where the data format can support it and not dependent on an attribute query, select or buffer

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">For example, a user turns on the display of a layer and the vector results are shown and a query template (datagrid?) results in a tab/div.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I would like to add the use case to this email thread so the mailing list understands what we are trying to accomplish. I would also like to hear from the
mailing list whether this would make for a good candidate to propose adding to the core code and in essence be the standard way GeoMoose would work with selection sets or should this become a documented alternative customization or possibly an extension if
possible. An example of this functionality was developed to work with GM 2.2 using a homegrown vector layer. We are now trying to port this functionality for use in GM 2.6 using the new vector layer support. See:

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Common Use Case: A user creates a selection results set of features by using the attribute query, select or buffer tools.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Result: The service would return the features to the map as a vector layer to visually show the results and display a query template results in tab.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Follow-up Use: A user would then be able to interact with that vector results set.<o:p></o:p></span></p>

<p class="MsoNormal" style="background:white"><span style="color:black">I’m currently working on porting the custom select tool to GeoMOOSE 2.6. The customizations enable direct interaction by using vector features for the selection result (instead of rendering
a raster image). This makes it possible to e.g. highlight an individual feature by clicking an icon in the result list. In the old custom code the service sent back commands to create the vectors in the <script> result of the service. I could replicate
this but would like to propose utilizing a WFS layer instead. This could be done in at least two ways:<o:p></o:p></span></p>

</span><span style="color:black">We could change the highlight layer in the mapbook to be a read-only WFS layer. This would also mean altering the highlight.map template in htdocs/php/select/ to enable WFS requests. select.php would work more or less as it
does now (but some of the rendering commands it sent back would be different).<o:p></o:p></span></p>

<p class="MsoNormal" style="background:white"><span style="color:black">2.)</span><span style="font-size:7.0pt;color:black">
</span><span style="color:black">We could try to utilize the OpenLayers GetFeature control which can be used to directly transform interaction with a WMS layer into WFS requests (see
<a href="http://openlayers.org/dev/examples/getfeature-wfs.html">http://openlayers.org/dev/examples/getfeature-wfs.html</a>). This would require the user to enable WFS in the mapfile for each layer they wanted the select service for. Since WFS supports spatial
filters, select.php would not be used (but we would need to a different way to render the HTML).<o:p></o:p></span></p>

<p class="MsoNormal" style="background:white"><span style="color:black">Either of these options would to need be configurable so that the current raster-based approach would still be available (especially when there is a potential for large selection result
sets).<o:p></o:p></span></p>
